WILLIAM R. BULLOCK, OF SYRACUSE, NEW YORK, ASSIGNOR OF ONE-HALF TO HARRYWIARD, OF SAME PLACE.

PLOW.

SPECIFICATION forming part of Letters Patent No. 244,179, dated July 12,1881. Application filed March 17, 1881. (No model.)

To all whom itmag concern:

Be it known that I, WILLIAM R. BULLocK,

. of Syracuse, Onondaga county, State of New York, have invented certainImprovements in 5 Flows, of which the following is a specifica- 1 o theconstructions of plows where the lower ends of the plow-haudles areaffi-xed to a brace between the mold-board and the standard orlandsidethat have, so far as my knowledge extends, been heretofore made therange of motion has '1 been limited too much for the purposes for whichmy invention is designed, and it is in this extended range of motion,and the means I "by which it is effected, that the novelty of my deviceconsists. The types of the devices here- 2 tofore tried are either toslide the handles sidewiseor to pivottheir lower ends at arstationarypoint on a permanent crossbrace on which the handles turn;

1 My improvement consists in giving motion Q 2 5- toflthelower ends ofthe handles from side to side along'a curved line'while the handles attheir upper junction with the 'brace-bar that spstains the'mare made to'traverse on a curve,

5 saidourves being, struck from an imaginary center ata point betweenthe two, regulated bythe range of motion desired for the han-' "dies.

'The construction is as follows,.ret'erring' to The plow on which myimprovement is placed in the drawings is like that heretofore patentedto Harry Wiard. There is a rocker, a, to which the lower ends of thehandles are attached. This rocker is curved between the trunnions at theends, as seen at a, Fig. 3, and has a curved slot through it, throughwhich a bolt or bolts pass, uniting the lower ends of the handles to thesaid rocker a, but allowing them a lateral movement for adjustment.

The adjustable brace bar b, as used in the above named patent forraising and lowering the handles, has curved slots 1) therein, throughwhich and the handles bolts pass to unite them together and hold them inplace. The curves in the rockera and in the brace-bar b are struck froma common center at the point c, Fig. 3,

- so located that by giving the handles free play at their lower endlaterally and at the bar b,

determined by the curved slots, as above stated,

I get a large range of motion for the upper ends of the handles, withthe limited space below, as indicated in Fig. l by dotted lines.

Having thus fullydescribed my invention, I claim- 1. The combination ofthe rocker a and bracebar I), having segmental curved slots thereincorresponding to a common center between the two,substantially as andfor the purposes specified. I

2. In combination with a mold-board and landside ofa plow, the segmentalslotted rocker a,slotted bar b, and plow-handles, in the manner and forthe purposes specified.
